Surface Finishes

PVD Vacuum Nitriding — Gold, Oil Slick, Black, Blue

Forms a dense metal nitride coating on the surface to enhance hardness and impact resistance. Deeply embedded into the metal surface, the color won't fade without heavy wear, even in rain and mud.

Electrolytic Anodizing — Green, Purple, Candy

Forms a protective oxide layer that increases surface hardness and corrosion resistance. The vibrant colors are created by natural light interference within the oxide film thickness—without using a single drop of dye.

Finish Notes

Candy Finish: Due to the anodizing process, the Candy finish features a fluid, randomly distributed multi-color pattern, meaning every set has a unique color flow.

Thread Appearance: White lines may appear around the threaded area of some colored bolts as a normal result of the coloring process. Please rest assured it does not affect performance or safe use.
